This backtrace doesn't say anything. Looks like another issue with glibc to me. But if the duplicate searches are correct the issue might be fixed. *** Bug 256196 has been marked as a duplicate of this bug. *** I'm gonna merge in some other "uncatched exception in Qt eventloop" bugs i googled up... this starts to get annoying... :-\ *** Bug 257794 has been marked as a duplicate of this bug. *** *** Bug 259155 has been marked as a duplicate of this bug. *** The problem about this bug is that "something" (*cough* i just blame plasma, cause it ... *cough*) throws an exception from a slot which isn't catched in the slot and enters the Qt eventloop which then - w/o any further detailed information just asserts (very smart implementation, indeed)
This so far didn't happen to me, ever.
Handling)
---------
If -> you have got a somewhat reliably way to reproduce the issue:
There a chance that info about the exception is printed to konsole when you run kwin from there ("kwin --replace &")
It can _maybe_ also be found in ~/.xsession-errors
You can run "gdb --args kwin --replace" and "catch throw" to have gdb catch throws and acquire a backtrace using "bt"
If you happen to compile Qt from sources, --- export QT_NO_EXCEPTIONS as CFLAG ---
This should produce a usable backtrace. ;-P

(because we cannot say whether all bugs derive from the same source) *** Bug 268642 has been marked as a duplicate of this bug. *** *** Bug 268902 has been marked as a duplicate of this bug. *** *** Bug 261832 has been marked as a duplicate of this bug. *** *** Bug 269214 has been marked as a duplicate of this bug. *** *** Bug 269387 has been marked as a duplicate of this bug. *** *** Bug 270873 has been marked as a duplicate of this bug. *** *** Bug 271118 has been marked as a duplicate of this bug. *** Git commit 505f7cc14a7ee9914a7d75128e28476ead34b9e0 by Thomas Lübking.
